This holiday, you are in charge of cooking the main course. Sure, you could make poultry (though we just had Thanksgiving Turkey).

And you could dive headlong into an elaborate celebrity chef recipe; stressing out every step of the way, hoping beyond hope that your Wellington turns out just right.

Might I suggest an easier recipe alternative? One with all of the pizazz and panache of a standing prime rib, but with a distinct flavor, and that is secretly SUPER easy to put together? Enter this Easy Lamb Roast.

Why You Should Make Lamb

  1. Lamb is delicious!
    • It’s got the familiar characteristics of beef, but with a tenderness and unique hint of earthy flavor that can only be found in some of the highest quality grass-fed red meat.
  2. Lamb is naturally nutrient rich!
    • A 3 oz. portion of Lamb offers almost half of your daily recommended protein! Read more about Lamb nutritional facts.
    • Ounce for ounce, Lamb has fewer calories, less saturated fat, more cancer-fighting CLA, and more Omega-3’s than beef.
  3. Lamb is ethically and environmentally responsible.
    • As foragers, sheep get all the nutrition they need from freely grazing to produce the highest quality meat and fiber that we consume.
    • Sheep naturally graze on land that otherwise has very limited agricultural value (hilly terrain) and actually improve their pasture land by cycling vital nutrients back into the soil; encouraging native plant growth, and reducing erosion.
  4. Lamb is Local!
    • With over 80,000 sheep farmers and ranchers in the U.S., (with 3,400 sheep farms in Ohio alone) fresh, local lamb is never far away.
    • The meat we used to develop this recipe came from the folks at Blue Heron Farms – winners of the Ohio Livestock Coalition’s Environmental Stewardship Award for its efforts to protect the air, land and water on and near their farm.

Why You Should Make This Easy Lamb Roast Recipe

First off, this Easy Lamb Roast will definitely feed a crowd. We used a 5-6lb bone-in lamb leg roast, and it easily fed 8 people with plenty of leftovers. (More on those in a minute).

Second, you won’t be struggling with difficult ingredients, or elaborate cooking techniques in order to get it made just right.

The seasonings couldn’t be more simple, and as long as you rely on a good meat thermometer to tell you when the meat is done cooking, the lamb itself is such a forgiving and naturally delicious piece of meat, you really can’t go wrong while cooking it.

Finally, this lamb roast will immediately be familiar as a holiday main course. A lamb leg roast looks enough like a beef roast, but has a more premium grass-fed/earthy taste, and it carves up like a bone-in ham. (For carving tips, check out this video)

In fact, if you’ve got picky eaters, don’t even tell them it’s lamb. Just sit back and wait until they start raving about how delicious it is.

The meat is juicy, tender, and it’s natural flavor shines whether you cover it in au jus, or top it with a mint sauce, chimichurri, or serve it with horseradish cream.

Plan For Leftovers

Like any good holiday main course, one of the best parts about a Lamb Leg Roast is the leftovers!

Unless you’re feeding an army, a 5-7lb roast should get you MORE than enough meat to feed everyone and send home some foil wrapped seconds.

Those can be heated up in the oven (still in their foil) at 350°F without risking cooking them more, so you can enjoy that tender meatiness again in sandwiches, potatoes, soup, tacos, or atop a salad.

BUT WAIT THERE’S MORE! You weren’t just gonna chuck that bone in the trash, right? Of course not! That sucker can make a dynamite lamb bone broth.

Definitely a consideration when choosing your leg of lamb cut at the butcher. If you go with “shank on” that just means an extra length of those bones, so if you’ve got plans to make some homemade lamb stock, be sure you choose that option.

Should I Marinate My Lamb Roast?

It doesn’t need it. Lamb is a very tender meat (especially a leg roast), so you’re unlikely to add tenderness through a long marinade process.

Plus, lamb is wonderfully flavorful by itself, so go easy on the added flavors. It doesn’t need much in the way of “soaked in” acids or sauces to add to the taste. Just a little sprinkle of seasoning before cooking goes a long way.

How to Make A Lamb Leg Roast

  1. Remove meat from packaging and set aside to allow it to come up to room temperature for about an hour.
  2. Chop up some rosemary and sage and slice 5 cloves of garlic (big slices).
  3. Using a knife, stab 1 inch deep holes all over the less fatty side of the roast (this will be the top), and several shallow long cross slices across the fat on the bottom.
  4. Rub the roast on all sides with olive oil, then push the slices of garlic into each of the holes in the meat.
  5. Sprinkle each side of the meat with salt and pepper and the chopped herbs (rosemary and sage), then place the roast fat side down in a roasting pan.
  6. Roast at 400°F for 20 minutes, then turn heat down to 350°F and continue cooking for about 2 hours for a 5-6 lb. roast.
  7. Temp with a meat thermometer and remove from oven when you are within about 5°F less than your desired doneness (145°F for medium rare: 160°F for medium).
  8. Tent with foil and let the roast rest for at least 15 minutes before carving.

FAQs

Should I sear a roast lamb before roasting? ›

For the perfect roast lamb, we recommend seasoning the surface of the meat, and then searing it, especially fat side down in a pan before roasting. Why bother with searing? Contrary to some stories, searing is less about locking in moisture, and all about improving the flavour!

What is the preferred cooking method for lamb? ›

It can be traditionally roasted but is best slow-roasted, pot-roasted or braised with liquid until practically falling apart. Shoulder can also be diced for stewing, or cut into shoulder chops. A pre-sliced roast is convenient, but it tends to dry out in the oven.

How do you keep roast lamb tender? ›

Lower temp = more succulent meat – Tough cuts like lamb shoulder need slow-cooking to tenderise them. The lower the roasting temperature, the less total moisture evaporation and thus juicier meat. 3-hour lamb is cooked at 180°C/350°F, while the 12 hour lamb is cooked at only 100°C/212°F.

How do you cook lamb so it's not tough? ›

Whether boneless or bone-in, the perfect leg of lamb should be either oven-roasted until blushing pink on the inside (with an internal temp around 130°F) or roasted long and slow for several hours until the meat is very tender and falls apart to internal temp around 175°F (I often use the slow cooker for that).

What happens if you don't sear your roast? ›

It's not really necessary to sear your roast before cooking, but caramelizing the surface gives the cut an incredible depth of flavor, enhanced with the complex layers of nutty caramel and coffee-like bitterness that meat-lovers find delicious.

What is the best oven temperature for lamb? ›

Roast leaner cuts of lamb in a hotter oven (450°F) to get a lovely brown crust and a well-cooked center; cook fattier cuts of lamb low and slow (325°F) to render all the fat and allow the lamb to cook in its juices. Due to residual heat, your lamb will continue to cook even after you pull it out of the oven.

What tenderizes lamb? ›

Baking soda / bi-carb and cornflour/cornstarch are the secret ingredients that tenderise the lamb meat. It's a technique called “velveting” that is used by Chinese restaurants, and it's the reason why the meat in your favourite Chinese dishes are always so soft.

Why is my lamb roast always tough? ›

When meat is sliced with the grain, it often results in tougher, chewier pieces. Follow this tip: The grain of the meat refers to the direction in which the muscle fibers run. Always slice lamb against the grain, cutting across the muscle fibers rather than with them.

How does Gordon Ramsay cook roast lamb? ›

And when you have a gorgeous cut, like a rack of lamb, you can cook it the good ol' Gordon Ramsay way—which is to say, lightly pan-sear it first, then baste it with an herby, garlicky butter, and finally finish it off in the oven until it's still pink and juicy in the middle. It comes out perfectly every time.

What removes gamey taste from lamb? ›

The distinct game flavor of either birds or animals will be milder after soaking the meat overnight in the refrigerator in either a salt or vinegar solution.

Is lamb better cooked slow or fast? ›

Slow cooking in liquid transforms tougher cuts of lamb into fork-tender meat. Neck, shoulder and belly, either diced or as whole joints, are the best cuts for slow cooking and need to be cooked for at least 2 hrs at 150C to soften the meat.

What is the cooking time for lamb per pound? ›

The lamb will need to cook for about 20 minutes per pound (2 hours for a 6-pound leg of lamb; 2 hours and 40 minutes for 8 pounds). An instant-read thermometer inserted in the thickest part of the meat, not touching the bone, should read 145 degrees when the lamb is medium-rare.

Should you brown lamb before cooking? ›

Browning the meat doesn't take long and has some advantages, including a good looking, caramelised surface and richer coloured dish. It can also give a deeper flavour, and some say a better texture.

Do you need to sear lamb before slow cooking? ›

Season your lamb shoulder with rosemary and garlic, or even just a little salt and pepper. Sear the lamb shoulder in a hot pan to seal in the flavours if you wish, this is not compulsory however, slow cooking it as is works just as well.

Should you sear a rack of lamb first? ›

Lamb rack is best seared in a pan and finished in the oven – this gives you lots of control over your cooking temperatures but still gives you a nice caramelisation on the surface of the meat. Be sure to remove the meat from the fridge before cooking so it can come to room temperature.

Is it better to sear a roast before slow cooking? ›

"Browning, or caramelizing, meat before putting it into a slow cooker isn't 100 percent necessary, but it is well worth the effort for the most flavorful and full-bodied end result," he says. "The caramelized surface of the meat will lend rich flavor and color to the finished dish."
